I'll post some pictures of them. They are the boards that are inside of the keyboard where the wiring and mylars are connected to.Ocean said:post pictures please
That's some great info lazersteve. I have lbs worth of them, and I still have keyboards I haven't taken apart yet, which will have all the pieces.lazersteve said:Those boards work great in M.A.M.E. ( Multiple Arcade Machine Emulator) cabinets when building your own arcade game. I've wired them to joysticks and push buttons as dedicated input devices in my MAME boxes. The key to getting them to work is to identify the Mylar key matrix attached to the processors board so you can define the key matrix when hard wiring the controls on the input board. It's also handy if you have the original keyboard cable that wires the card to the computer. If you need any type of human feedback based computer software these boards are easily adapted since they convert a matrix of up to 100+ inputs into USB or PS2 data which any computer can understand.

Why should it be tin coated gold? If it's tin coated then there is no gold.wrmahaff said:Dumb question, but the silver/greyish colored finger is actually a tin coated gold finger?

Rub it against a piece of paper, if it leaves a grey streak then it is tin.
I think I've seen some carbon "plated" fingers in some keyboards but never any gold plate in over 100 keyboards.

That's what has me confused. The picture above references a "gold finger", but all I see is tin. I'm trying to figure out what I'm missing because every other finger that wasn't gold colored I was taught/told wasn't gold or worth refining.

Are you talking about that metal piece that is attached to the board on the top? If you are, then that piece slides right off and the gold fingers is under that. Also, not all boards have gold fingers, as you can see from the other boards I put there just for reference.

Can you let me know when you mail them so I know when to start looking for them.tek4g63 said:Jack,
I don't currently have any lying around. But when I get some more keyboards to tear down I'll send these to you, no charge. I have a friend that may have a few old keyboards laying around. I'll make the call today.
